Seeing the Mick Jagger film "Performance" (1970) in the late '70s, was intrigued by the vintage BDSM clips used in a scene set in a sleazy theater. It only took 30 years to locate the actual stag reel. This has some pretty explicit porn content that had to be edited here. But you can see the entire public domain film on "Vintage Erotica anno 1940" (Cult Epics).
